Check Digit Verification of cas no

The CAS Registry Mumber 7189-71-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,8 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7189-71:
(6*7)+(5*1)+(4*8)+(3*9)+(2*7)+(1*1)=121
121 % 10 = 1
So 7189-71-1 is a valid CAS Registry Number.

Solvolysis of N-(Chlorosulfinyl)diarylketimines

Al-Talib, Mahmoud,Tashtoush, Hasan

, p. 611 - 612 (2007/10/02)

N-(Chlorosulfinyl)diarylketimines 1a - c readily react with alcohols, phenols and thiophenol to give good yields of dialkyl sulfites, diaryl sulfites and dithiosulfites, respectively, besides (diarylmethylene)ammonium chlorides 3a - c.The reactions of 1a with water and carboxylic acids have also been studied.
